To all whom it may concern: y Be it known that l, lVALTeR C. KEMPTON,

a citizen of the'United Statesfresidingjat' San Francisco, in thc county lof ASan Francisco, yState of Callfornia, have 1n1-'entedLcertain new useful lmprovements in Heels of which the follow ing 1s a specification.

lily invention relates to new and useful irnproveineY in rubber heels and bottoms 'ft-ir boots and shoes and has for its objects tc prevent slipping by their engagement with the surfaces upon which the h eels rest, and to reinforce the wearing surfaces o1" parts of rubber heels so asvto increase their durability andusefulness. v

t ann to provide a form of reinforced and uoirslippable rubber heel which will be serviccable and can be manufactured at low cost. I"l'he accompanying drawings, which form a part of this specification, illustrate forms y of reinforced rubber heels 'constructed in accordance with my invention.

.ln the said drawings: Figure l is a plan View of a heel with a portion of the rubber broken away showing a-coil in place. Fig. 52 is an elevation of the saine. F ig. 3 is a broken plan View showing an archedv wire within the coil. Fig. fl is a broken elevationview showing a coil elliptical in shape; and 7 tigg is a plan view of a heel with a portion of the rubber broken away showing a coll circular 1n forin with a segment of 1ts circumference parallel with the segmentl of the circle formed bythe heel.

ln the invention, wire, preferably of steel, is coiled `and inserted longitudinally in the rubber within the periphery of the heel parallel with the whole or a part of its segment, as may be desired, and with it-s one surface in substantially the same plane as ,the lowermost surface of the heel. It is preferable that the wire coil have equa-l resiliency with the rubber so thatv none of the advantages of the rubber heel be lost; l prefer using a coil elliptical in shape, as shown in Fig. 4, as a greater portion.y ofr metallic .surface can be placed closer to the bottoni or outer surface at the lower plane of the heel, adding to the support of the rub` ber and providii'ig a greater wearing metal surface at the par of the heel where the wear is the greatest. This coil can be placed within the whole or a part of the peripheryl of the heel desired.

ln Fig. 3 is shown a metal strip,l or wire,

`cuiyed to conform with the periphery ofthe 4taining the coil in heel placed within the'coil wire. lt is designed to hold'the coil in place during the process of manufacture and to assist in re-v place should any part of' therubber be worn or broken do not-'restrict myself to its use. v

At Fig.' y5 l show a wire coilforming a complete circle. Thiscircle is of such diameter as yto be less'than the diameter ofthe segment of the circleV formed by the curved portionofthe heel and the coil so 4formed is so placed withinthe rubber that a segment away but I .ofits'circu1n-ference parallelsthat of the segment of the lcircle formed by the curve of the heel. l

A plurality of perforatedmetal disksor washers are inserted `in the rubberas shownwithin the rubber within and fclose )in Figs. 1, 2 and 3 and in the rubber are with the outer edge of said heel, the lower v surface of said coil lying in substantially the same plane as the lowermost surface of the heel. 2. A rubber heel, a wire coil inserted longitudinally within the rubber within and close to the periphery of the heel, a portion of said coil being parallel with the real-most curved edge of the heel, said coil having its lower surface in substantially the same plane as the lowermost surface of the heel.

3. A, rubber heel, an-elliptical wire coil inserted longitudinally within the rubber withinand close to the peripheryofthe heel and parallel with the outer edge of said heel,

said coil having its lower surface in substantially the same plane as the lowermostsurface ofthe-heel, and a metal core within the wire coil.

In ltestimony vwhereof I have alixed my signature in the presence of two-witnesses this 25 day of J une 1908.
